what is the thermodynamic process taking place when we use pressurized spray cans and the can outside surface & the spray become cold? Examples include deodorant sprays, Barbassol shaving cream, Keyboard Air dusters, Pressurized Tire, hair sprays and more.
That is an isenthalpic process, which is not quasistatic, and work done by the gas does not equal the integral of P*dV on this plot. The enthalpy before and after expanding through the valve is equal. The process is irreversible, since the work the gas attempts to do, turns into heat generated by friction. Isenthalpic processes may or may not cause the gas to cool, depending on the identity of the gas. Most gasses do cool in an isenthalpic process, but a select few actually increase in temperature. This is called the Joule-Thompson effect.
Could you please show some real life example of an isothermal process in nature? Is cloud formation an example of the isothermal process? Is precipitation or rainfall, snow, flurries, a good example of the isothermal process. Refrigerant phase change to liquid at a constant temperature in condenser outside and the refrigerant phase change to vapor in an evaporator at a constant temperature inside are examples of Isothermal Process? Please verify. Boilers produce saturated steam at a constant temperature is an example of an isothermal process, please verify?
Thanks for the super nice explanation!
i like your videos mate, very helpful and clear
The new Sal Khan? I think yes!!
thanks a lot , really clear!!!!

youre so good
Boiler, evaporator, condenser, spray cans are examples of isothermal process?
Boiler, evaporator, and condensers are examples of isobaric processes.
Spray cans are isenthalpic processes

Please verify.

The compression & power stroke in an Internal Combustion Engine are governed by the adiabatic process, please verify, thanks?
In the ideal case, yes.
